"Remove Kabab"

On various sites and meme pages there has been something popping up and I cannot quite find the answer, the video: Serbia Strong. It confuses me because people keep saying "Remove Kabab" and idea what this means ?

Its a parody video
Serbia Strong is a music video made by 3 serbian army members, a trumpet player, an accordion player and a keyboard player, favouring the first bosnian president Radovan Karadžić of the Republika Srpska and being strong for their country. The music video gained a big popularity on YouTube by making several parodies.
